Rapper Gucci Mane's prison term has been shortened by 12 months.

The Icy hitmaker, real name Radric Davis, was sentenced to 39 months in jail after pleading guilty to a gun charge in August (14).

The charge stemmed from incidents last year (13), when he was caught in illegal possession of a weapon by police officers.

His lawyers asked a judge to consider giving him credit for time served and the request was granted this month (Sep14).

According to Tmz.com, his 39-month sentence will now end in December 2016. Upon his release, the star will be supervised for a further three years and limitations will be placed on his travel.
